I don’t think so - from how i understand it, everything where you upload a file to a server to edit it there wouldn’t work at all.
The flow looks like this:
You select a file for upload - the browser creates a file in OPFS storage representing the original file - any change you make serverside are replicated to the copy in OPFS storage - when you save the file, you don’t actually have to download it, but the file gets moved from OPFS to wherever you save the file. This prevents long downloads and a lot of warnings and the file in OPFS storage is encrypted because of HTTPS.
I wonder if librewolf has this option on by default
